Important Operator Safety Instructions
WARNING: This powerful cutting machine is capable of amputating hands and feet and can throw objects
that can cause injury and damage! Failure to comply with the following SAFETY instructions could result in
serious injury or death to the operator or other persons. The owner of the machine must understand these
instructions and must allow only persons who understand these instructions to operate machine. Each
person operating the machine must be of sound mind and body and must not be under the influence of any
substance, which might impair vision, dexterity or judgment. If you have any questions pertaining to your
machine which your dealer cannot answer to your satisfaction, call or write the Customer Service
Department at SNAPPER, McDonough, Georgia 30253. Phone: (1-800-935-2967).
Protection for Children
Tragic accidents can occur if the operator is not alert to the
presence of children. Children are often attracted to the
machine and the mowing activity. Never assume that
children will remain where you last saw them.
1. KEEP children out of the mowing area and under the
watchful care of a responsible adult other than the operator.
2. DO NOT allow children in yard when machine is operated
and turn machine OFF if anyone enters the area.
3. DO NOT allow pre-teenage children to operate machine.
4. ALLOW only responsible adults & teenagers with mature
judgment under close adult supervision to operate machine.
5. DO NOT pull mower backwards unless absolutely
necessary. LOOK and SEE behind and down for children,
pets and hazards before and while backing.
6. USE EXTRA CARE when approaching blind corners,
shrubs, trees, or other objects that may obscure vision.
Slope Operation
1. Slopes are a major factor related to slip and fall acci-
dents, which can result in severe injury. All slopes require
extra caution. If you feel uneasy on a slope, DO NOT mow
it.
2. Mow across slopes, never up-and-down. Exercise
extreme CAUTION when changing directions on slopes. DO
NOT mow steep slopes or other areas where stability or
traction is in doubt. Refer to the Slope Guide at the end of
this manual.
3. Use extra care with gcrass catchers or other attach-
ments; these affect the handling and the stability of the
machine.
Preparation
1. Read, understand, and follow instructions and warnings
in this manual and on the mower, engine and attachments.
Know the controls and the proper use of the mower before
starting.
2. Only mature, responsible persons shall operate the
machine and only after proper instruction.
3. Data indicates that operators age 60 and above, are
involved in a large percentage of mower-related injuries.
These operators should evaluate their ability to operate the
mower safely enough to protect themselves and others
from serious injury.
Preparation
(Continued From Previous Column)
4. Handle fuel with extra care. Fuels are flammable and
vapors are explosive. Use only an approved fuel container.
DO NOT remove fuel cap or add fuel with engine running.
Add fuel outdoors only with engine stopped and cool. Clean
spilled fuel and oil from machine. DO NOT smoke.
5. Check the area to be mowed and remove all objects such
as toys, wire, rocks, limbs and other objects that could
cause injury if thrown by blade or interfere with mowing.
Also note the location of holes, stumps, and other possible
hazards.
6. Keep people and pets out of the mowing area.
Immediately, STOP Blade, Stop engine and Stop mower if
anyone enters the area.
7. Check shields, deflectors, switches, blade controls and
other safety devices frequently for proper operation and
location.
8. Make sure all safety decals are clearly legible. Replace if
damaged.
9. Protect yourself when mowing and wear safety glasses, a
dusk mask, long pants, and substantial footwear. DO NOT
mow barefooted or with sandals.
10. Know how to STOP blade and engine quickly in
preparation for emergencies.
11. Use extra care when loading or unloading the machine
into a trailer or truck.
12. Check grass catcher components frequently for signs of
wear or deterioration and replace as needed to prevent
injury from thrown objects going through weak or torn
spots.
Safe Handling of Gasoline
To avoid personal injury or property damage, use extreme
care in handling gasoline. Gasoline is extremely flammable
and the vapors are explosive.
1. Extinguish all cigarettes, cigars, pipes and other sources
of ignition.
2. Use only an approved fuel container.
3. DO NOT remove fuel cap or add fuel with the engine
running. Allow the engine to cool before refueling.
4. DO NOT refuel the machine indoors.

or trailer bed with a plastic liner. Always place the contain-
ers on the ground away from the vehicle before filling.
7. Remove gas-powered equipment from the vehicle or
trailer and refuel it on the ground. If this is not possible,
then refuel equipment using a portable container, rather
than a gasoline dispenser nozzle.
8. DO NOT start gas powered equipment in enclosed vehi-
cles or trailers.
9. Keep the nozzle in contact with the rim of the fuel tank or
container opening at all times until fueling is complete. DO
NOT use a nozzle lock-open device

roads, and under any conditions where thrown objects
might be a hazard.
3. Mow only in daylight or good artificial light.
4. DO NOT operate mower while under the influence of
alcohol or drugs.
5. After striking a foreign object or if mower vibrates
abnormally, STOP the engine, disconnect and secure spark
plug wire. Inspect the mower for any damage and repair the
damage before starting.
6. DO NOT mow near drop offs, ditches or embankments.
Operator could lose footing or balance.
7. STAY ALERT for holes and other hidden hazards. Tall
grass can hide obstacles. Keep away from ditches,
washouts, culverts, fences and protruding objects.
8. DO NOT mow on wet grass. Always be sure of your
footing. Keep a firm hold on the handle and walk, never run.
Slipping could cause injury.
9. ALWAYS stay behind handle when engine (motor) is
running.
10. DO NOT leave the machine with the engine running.
STOP BLADE and STOP ENGINE before leaving the opera-
tors position for any reason.
11. Before cleaning, repairing or inspecting make certain
engine, blade and all moving parts have STOPPED.

prevent accidental starting.
12. STOP engine and wait until the blade comes to com-
plete STOP before removing grass bag and/or clearing
grass.
Operation
(Continued From Previous Column)
13. DO NOT operate mower without the entire grass catch-
er, or guards in place discharge guard, rear guard or other
safety devices in place and working. DO NOT point dis-
charge at people, passing cars, windows or doors.
14. DO NOT discharge material against a wall or obstruc-
tion. Material may ricochet back towards the operator.
15. Slow down before turning.
16. Watch out for traffic when near or crossing roadways.
17. DO NOT operate engine in enclosed areas. Engine
exhaust gases contain carbon monoxide, a deadly poison.
18. Only use accessories approved by the manufacturer.

ance. Allow engine to cool before storing machine in an
enclosure. Store fuel container out of reach of children in a
well ventilated, unoccupied building.
2. Keep mower and engine free of grass, leaves or excess
grease to reduce fire hazard and engine overheating.
3. When draining fuel tank, drain fuel into an approved
container outdoors and away from open flame.
4. Keep all bolts, especially blade bolts, nuts and screws
properly tight. Check that all cotter pins are in proper
position.
5. Always provide adequate ventilation when running
engine. Engine exhaust gases contain carbon monoxide, a
deadly poison.
6. Service engine and make adjustments only when engine
is stopped. Removed spark plug wire from spark plug and
secure wire away from spark plug to prevent accidental
starting.
7. DO NOT change engine governor speed settings or
overspeed engine.
8. Check grass bag assembly frequently for wear or
deterioration to avoid thrown objects and exposure to
moving parts. Replace with new bag if loose seams or tears
are evident. Replace slider or bag adapter if broken or
cracked.
9. Mower blades are sharp and can cut. Wrap the blades or
wear heavy leather gloves and use CAUTION when handling
them.
10. DO NOT test for spark by grounding spark plug next to
spark plug hole; spark plug could ignite gas exiting engine.
11. Have machine serviced by an authorized SNAPPER
dealer at least once a year and have the dealer install any
new safety devices.

Maintenance - Introduction
To retain the quality of the mower, use genuine SNAPPER
replacement parts only. Contact a local SNAPPER dealer for
parts and service assistance. For the correct part or
information for a particular mower, always mention the
model and serial number.
Service - After First 5 Hours
Change Engine Oil
1. Refer to the Engine Manual for proper oil specifications,
procedures and proper service intervals.
2. For the simplest/cleanest oil change, simply turn the
mower on its side to drain the oil, as shown. Drain the
oil through the dipstick tube (A, Figure 16) into a
container. Allow sufficient time for all the oil to drain.
Important: Drain the fuel tank before tipping the machine.
DO NOT tip the machine with the carburetor or spark plug
down. Oil from the crankcase will saturate the air filter and
cause the engine to be hard to start or not start at all. If
contamination does occur, the air filter will have to be
replaced.
3. Dispose of drain oil properly.
4. Fill the engine with oil as specified in the Engine Manual.
Do not overfill.
Check Grease Level in Transmission
1. Remove the transmission fill plug (A, Figure 17). Roll
the machine forward or backward while looking down
into the plug hole.
2. If liquid grease is not visible on the input gear (the small
gear below the plug hole), add an amount, to cover the
gear, of Snapper “00” grease.
Note: Snapper “00” grease (Part No. 7029443) is available at
your Snapper dealer.
Note: Do not spill grease or oil onto the surface of the drive
disc
(A, Figure 18)
.
3. Reinstall the transmission plug.
4. Check the grease level after each 25 hours of operation.
Important: Drain the fuel tank before tipping the mower. DO
NOT tip the machine with the carburetor or spark plug down.
Oil from the crankcase will saturate the air filter and cause
the engine to be hard to start or not start at all. If
contamination does occur, the air filter will have to be
replaced.
